SIGNALING DEVICE.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed June 24, 1916. Serial No. 105,759.

ful Improvements in Signaling Devices, of

which the following is a specification, reference being had to the accompanyingdrawings.

This invention relates to certain improvements in signaling devices and has relation more particularly to a device of this general character which serves to operate a signal when water has reached a predetermined level, and it is an object of the invention to provide a novel and improved device which is operable under the influence of a buoyant body.

Furthermore it is an object of the invention to provide a novel and improved device of this general character especially designed and adapted for use in connection with a drip pan for refrigerators or the like, and which includes an audible signal wherein the operation thereof is under control of a trip together with a buoyant body adapted to be positioned within the drip pan and which serves to actuate the trip when the water within the pan has reached a predetermine l level.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved signaling device whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in elevation of a signaling device constructed in accordance with an embodiment of our invention, the coacting pan being shown in fragment; and Fig. 2 is a vertical sectional view taken through the device as disclosed in Fig. 1.

As disclosed in the accompanying drawings, P denotes a drip pan of conventional form and which is generally employed in connection with refrigerators or the like, and

S denotes as an entirety my improved signal.

As herein embodied, our improved signal includes a plate 1 of predetermined configuration having operatively engaged therewith an audible signal herein disclosed as including a bell 2 and a striker 3 operable under the influence of the spring motor 4. The motor 4 includes a toothed wheel 5 with which coacts the trip 6 whereby the signal S is normally maintained inoperative. EX- tending upwardly from the plate 1 is a tube 7 terminating in the laterally directed extension 8 which is adapted to overlie the upper edge of the pan P and has its inner end in communication with the depending guide member 9, .one face of which is open. Arranged within the guide member 9 is a buoyant body 10 preferably of cork which is adapted to rise with the level of the water collected within the pan P and when said body 10 reaches a predetermined point it is brought into contact with the lower end of the depending portion 11 of the wire W which isdisposed through the extension 8 and downwardly through the tube 7 and has its lower end formed in the hook member 12 operatively engaged with the trip 6 in order to disengage the same from the toothed wheel 5 when the wire W is elevated under the influence of the buoyant body 10 in order to permit an audible signal to be given when the water within the pan P has reached a predetermined level. Coacting with the trip 6 is a retractile member 14:, herein disclosed as a conventional coil spring, which serves to normally maintain the trip in operative engagement with the wheel 5.

From the foregoing description, it is thought to be obvious that a signaling device constructed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that our in vention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several 5 1. In combination with a container,

plate, a motor-operated signal carried by the plate and including atoothed wheel, a trip normally engaged with said Wheel for rendering the signal inoperative, a guide is carried by the plate and extending Within the container, a buoyant body loosely mounted Within the guide, and a member engaged with the trip and terminating above the buoyant body, said member being moved. in

15 one direction bythe buoyant body to release the trip from the toothed Wheel.

2. In combination With a container, a plate, a motor-operated signal carried by the plateand including a toothed Wheel, a

2G trip coacting With the toothed Wheel for-rendering the signal inoperative, a guide carried by the plate and disposed Within the container, a buoyant body positioned Within the guide, a member operatively engaged with the trip and terminating above the buoyant body and. adapted to be'engaged thereby to move the member in one direction to disengage the trip from the toothed Wheel, and means coacting With the trip for normally maintaining the same in operative engagement with the toothed Wheel. said means also serving to hold the member at the limit of its movement ina direction opposite to that imparted thereto by the buoy ant body.

In testimony whereof We hereunto aifix our signatures in the presence of two witnesses.
